| Abstract: | The factors that affected heat-resistance of dehydrogenated RTV silicone rubber were studied by TG and thermal aging,including types of silicone rubber and catalysts,amount of hydrogen silicone oil and types of filler.The result showed that all these factors could influence the heat-resistance of silicone rubber.The preferred composition was silicone rubber 100 phr,catalyst 1 phr,hydrogen silicone oil 2 phr,and filler 30 phr. |
